Abstract

The authors report the synthesis and characterization of two-dimensional (2D) single crystalline nanonetworks consisting of tungsten oxide nanowires with diameters of ca. . The 2D networks are believed to result from the nanowiregrowth along the four crystallographic equivalent directions of ⟨110⟩ in the tetragonal structure. These 2D tungsten oxide networks may be potential precursors for creating 2D networks comprising nanotubes.
